Passive standing tests for the office diagnosis of postural tachycardia syndrome: new methodological considerations,<\/a> by Maria Roma, Colleen L. Marden & Peter C. Rowe in\u00a0Fatigue: Biomedicine, Health & Behavior<\/em> 2018 [Published online: 25 Aug 2018]<\/h3>\n

Research abstract:<\/strong><\/p>\n

Background:<\/b>\u00a0Passive standing tests are a first-line, practical means of assessing individuals with chronic orthostatic symptoms.<\/p>\n

Purpose:<\/b>\u00a0To identify the proportion reaching heart rate (HR) criteria for postural tachycardia syndrome (POTS) during a 10-minute passive standing test (PST) if measurement of the lowest supine HR incorporated a 2-minute period of post-test monitoring, rather than being restricted to the 5-minute pre-test values only, and to determine the proportion whose POTS would be missed by shorter periods upright.<\/p>\n

Methods:<\/b>\u00a0Consecutive individuals\u2009\u2265\u200912 years from 2008 to 2017 who presented with chronic fatigue or lightheadedness and whose PST met criteria for POTS.<\/p>\n

Results:<\/b>\u00a0Of the 93 enrolled (70% female, median age 17 years), the mean (SD) HR was higher in the 5\u2005min supine before the 10\u2005min upright than in the 2\u2005min supine afterwards (67.6 [10.0] vs. 65.7 [10.9];\u00a0P<\/i>\u2009=\u20090.01). Thirteen (14%; 95% CI, 7\u201321%) satisfied HR criteria for POTS using the supine HR from\u00a0only<\/u>\u00a0the post-test period. The median time to reaching the HR criteria for POTS was 3\u2005min. Of those reaching HR criteria, 53% (95% CI, 43\u201363%) would be missed by a 2-minute and 27% (95% CI, 19\u201337%) by a 5-minute test.<\/p>\n

Interpretation:<\/b>\u00a0More adolescents and young adults are diagnosed with POTS during a 10-minute PST when the definition of their lowest supine HR includes a 2-minute post-test measurement along with the conventional pre-test measure. A full 10\u2005min of standing is required to avoid underdiagnosing POTS in both clinical and epidemiologic studies.<\/p>\n","protected":false},"excerpt":{"rendered":"
